Monitoring
Requirement
2.1.1 In
accordance with the approved EM&A Manuals, 24-hour Total Suspended
Particulates (TSP) monitoring at the designated air quality monitoring station is
required. Impact 24-hour TSP monitoring should be carried out at least once
every 6 days. In case of complaints, 1-hour TSP monitoring should be carried
out at least 3 times per 6 days when the highest dust impacts are likely to
occur.
2.1.2 The monitoring equipment, monitoring methodology and monitoring schedule
are detailed in the monthly EM&A Reports for EP-451/2013 prepared for Contract No. ED/2018/04.
2.2.1 According to
the EM&A Manual, three air quality monitoring locations, namely KTD1, KTD2
and KER1, are covered by this Contract within the South Apron Area of Former
Kai Tak Airport. The other two air quality monitoring locations, which are
identified in Cha Kwo Ling area, are farther than 500m away from the site
boundary and thus not covered by this Contract. The monitoring works in Cha Kwo
Ling area are covered by Contract No. ED/2018/04.
2.2.2 According to
the approved alternative baseline air quality and noise monitoring locations
(EPD reference: EP2/K19/A/21 pt.5), the original monitoring locations (KTD1,
KTD2 and KER1) are proposed to be replaced by alternative monitoring locations
(KTD1a, KTD2a and KER1a) for air quality monitoring.
2.2.3 According to
the approved relocation of monitoring location KER1a (EPD reference: () in
EP2/K19/A/21 pt.5), the monitoring location KER1a are proposed to be relocated
by alternative monitoring location KER1b for air quality monitoring.
2.2.4 According to
the approved relocation of monitoring location KTD2a (EPD reference: () in
EP2/K19/A/21 pt.6), the monitoring location KTD2a are proposed to be relocated
by alternative monitoring location KTD2b for air quality monitoring.
2.2.5 According to
the approved relocation of monitoring location KTD2b (EPD reference: () in
EP2/K19/A/21 pt.7), the monitoring location KTD2b are proposed to be relocated
by alternative monitoring location KTD2c for air quality monitoring.
2.2.6 As informed by the ET of Contract No. ED/2018/04, the monitoring location
KTD1a and KER1b have been relocated to KTD1 and KER1 for air monitoring on 3
August 2020.
2.2.7 The most
updated locations are summarized in Table 2.1 and shown in Figure 2.
2.3.1
The monitoring results and observations for KTD1, KTD2c and KER1 are
reported in the Monthly EM&A Reports for EP-451/2013 prepared for Contract
No. ED/2018/04.
2.3.2
One Action Level exceedance for 24-hr TSP were recorded in the reporting
month. An exceedance were recorded at KER1 on 23 December 2020.
2.3.3
One Limit Level exceedance for 24-hr TSP was recorded in the reporting
month. An exceedance was recorded at KTD2c on 29 December 2020.
2.3.4
No Action / Limit Level exceedance was recorded for 24-hr TSP at KTD1 in
the reporting month.
2.3.5
On 23 December 2020, at KER1 non-project related construction works were
carried out during 24-hr TSP monitoring. Dust was arising from the road traffic
along Kai Hing Road and vehicle movement from the adjacent building (Kerry DG
Warehouse (Kowloon Bay), also generated from construction site of Trunk Road T2
when breaking and excavating activities were processing. Thus, it is considered
that this exceedance is not project related.
2.3.6
On 29 December 2020, at KTD2c non-project related construction works
were carried out during 24-hr TSP monitoring. Dust generated from construction
site of Trunk Road T2 when breaking activities were processing. Thus, it is
considered that this exceedance is not project related.
2.3.7
No complaint of air quality was received. Therefore, no impact 1-hour
TSP monitoring was conducted in the reporting month.
2.3.8
The weather
conditions during the monitoring are provided in Appendix F.
